2nd Gen Non-Engine/Transmission no start, no fuel transfer pump coming on

[emarsh]

wife drove it and parked in driveway, when I went to move it, no start. 42k miles and the dealer replace the injection pump and installed an IN TANK lift pump. Last week I noticed the pressure was low, about 5 psi. It never had more than 7 with the new pump and the same gauge I had before. I'm afraid the pump has died, still showing 1/8 th fuel tank level. Darn we have put less than 3k miles since the new pump was installed.

should I drop the tank or is there an easier way to check; where is a good spot to trace the wire from the ECM to the pump?

I am wondering if your fuel level sender may have gone bad. It has happened quite frequently that people have run out of fuel thinking they still had plenty left. I would suggest adding fuel as a first step to make sure that's not the issue. Of course if you have to drop the tank to replace your lift pump, it will be that more difficult to do.

Have you checked the fuel pump relay to make sure it's not the issue?

You can always try energizing the pump directly, bypassing everything else to see if it's functioning or not.

Try adding some more diesel to your tank. I think the pickup may be higher with the replacement pump (someone correct me if I am wrong).

Yes but I should hear the lift pump come on when the key is turned to "on"

I lost the pre start pump 1 sec run, but the engine would start fine (summer). I could tell because I also lost the wait light (& grid heaters). It was cured with a reflash of the ecu. Try the engine 20 sec crank and see if the pump runs the 25 sec. before timming out.
